摘要：
In this paper, we propose a nonstop system upgrade method without significant performance degradation for data management software. To reduce disk accesses and network traffic, we construct logical nodes inside a physical node and migrate data between the symbiotic logical nodes. This logical migration is assisted by storage management functions that hide data location and migration from users. We also show the effectiveness of our method using experimental results on the system based on the Autonomous Disks we have proposed as a highly available storage system technology. © 2006 Wiley Periodicals, Inc.
